            Dictionary<string, string> data = new Dictionary<string, string>();

            client.Post("/1038145769594318/feed", new
            {
                message = " test page post",
                picture = "http://service.extrabucks.in/EmailTemplateCss/7/images/bottom-background2.png",
                name = "Nikunj Patel",
                link = "www.extrabucks.in",
                description = "Test Description",
                type = "links"
            });
        }
    }

嘿，我使用这个代码在Facebook上张贴使用c#，但问题是，它不是张贴作为一个页面，它的张贴作为一个用户。我想张贴作为一个页面在我的粉丝页。请给我一个解决方案使用上述代码。还有一件事，我想终身工作access_token我该怎么做?提前感谢

在facebook页面上使用c#作为使用graph api的页面

public static string GetPageAccessToken(string userAccessToken)
    {
        FacebookClient fbClient = new FacebookClient();
        fbClient.AppId = "*****";
        fbClient.AppSecret = "**************";
        fbClient.AccessToken = userAccessToken;
        Dictionary<string, object> fbParams = new Dictionary<string, object>();
        JsonObject publishedResponse = fbClient.Get("/me/accounts", fbParams) as JsonObject;
        JArray data = JArray.Parse(publishedResponse["data"].ToString());
        foreach (var account in data)
        {
            if (account["name"].ToString().ToLower().Equals("opening shortly"))
            {
                return account["access_token"].ToString();
            }
        }
        return String.Empty;
    }

这个代码为我工作，每次刷新页面访问令牌

just add 

client.Post("/1038145769594318/feed", new
            {
                message = " test page post",
                picture = "",
                name = "Nikunj Patel",
                link = "www.extrabucks.in",
                description = "Test Description",
                type = "photo",
                 access_token = GetPageAccessToken(access_token)
            });
